IMPROVEMENT IN TBIVIPLIZS FOR yLOOMSl etti Segnale maar it in tigenttttcrt fgztttnt mit uniting wat of tigt sante.,

TO ALL PERSONS 'IO WIIOM THESE PRESENTS MAY COME:

Be it known that I, WARREN W. DUTGHER, of Hopedale, in the county ofWorcester, and State of Massachusetts, have made a new and usefulInvention or Improvement having Reference to Roller Temples for weavingcloth; and I do hereby declare the same to be fully described in the'following specification, and represented in the accompanying drawings,of which- Figure 1 is a top View, and i 1 Figures 2 and 3 aresections ofone of my improved temples, the second of such sections being throughand in line of the axis ofthe toothed roller of the temple. 4

The mode heretofore adopted for fastening the roller-spindle in placehas been by a screw, eut either on its inner end Vor next to its head,such being as shown in Letters Patent, No. 37,954, bearing date the 24thday of March, 1863, and No. 53,423, bearing date the 27th day of March,1866, both of such patents having been grantedto me.

In practice, it has been found that the screw is` liable to and doesoccasionallygwork loose or unscrew, so as to allow the toothed roller tobe borne up bythe cloth, and revolved against the. cap,`in which casethe points or teeth of the roller are almost sure to be dulled orinjured to such an extent as to either seriously impair the efficiencyof the roller or render it useless, and require another to besubstituted for it. Besides oeeasioning the loss of a roller, Atheaccident is often attendedv with other and greater losses, such asinjury to the cloth, and expenditure of time and labor necessary to thestoppage of theloom, and the substitution of a new or perfect roller inthe temple-trough.

The object of my present improvement is to render the roller-spindle oraxle so fixed that its position is not dependent on a screw eut on suchspindle, but is insured by other means.

To accomplish this, I form in the standard ofthe trough, and in theclosed inner end of the cap, sockets,

closed at their outer ends, to receive the spindle at its two ends, andhold it firmly in place, when the cap is lfastened to the standard bythe screws employed to confine the two together.

In the drawings, A denotes the toothed roller, and B the spindlethereof; the latter, in this case, being a short rod 0r piece ofcylindrical wire, of the proper diameter and length. A

D is the trough,and C the cap thereof, the latter being fastenedbyscrews a a to a standard, E, erected on the outer edge of the trough.

In the inner side of the said standard is a socket, b, which opens onlytoward the trough. There is also s'uch a socket,c, made'in the inner endor part, d, ofthe cap. The axes of both these sockets arel to be in linewith' that of the toothed roller, and into these sockets the two ends ofAthe spindle B are to be placed, the distance between the mouths of cachof the two sockets and the base of the other being less than the length`of the spindle, in order that the spindle may not fall out ofthesockets.

I prefer, however, to have the distance between the bases ofthe socketsequal to the length of the spindle, as in that case, the spindle, whenin the sockets, can have no endwise motion.

I would remark that I make no claim to constructing the temple-troughstandard, and the inner end part of the cup, with holes going throughthem, as it is usual to make them to receive a spindle, to be screwedinto either of such holes.

What I claim as my present improvement, isy v The temple, constructedsubstantially as described, the trough-standard, and the inner 'end ofthe overhanging c ap, being provided with sockets, closed" at theirouter ends, such sockets being to receive andlhold the roller-spindle inplace, in manner es set forth.'
